The brown Adelaide brogues in the photo came out of storage the other day for the first time since March. They and the boots have replaced the spectators, white bucks and tan shoes of summer in the active rotation.
The shade that most makers call chestnut is useful as a rough boundary between spring and fall shoe colors. In the sunshine of spring, chestnut tends to be as dark a brown as a man needs, with some exception granted to chocolate brown suede. And in the gloomier days of fall and winter, it fills the reverse role as the lightest shade in the closet. Generally, dark oak and espresso look better.
Autumn is here. Wear darker brown shoes.
